Fundamental Counting Principle and Simple Probablity

Front

What is the Fundamental Counting Principle?

Back

The Fundamental Counting Principle states that if one event can occur in 'm' ways and a second event can occur independently in 'n' ways, then the two events can occur in m x n ways.

What is theoretical probability?

Back

Theoretical probability is the probability of an event based on the reasoning behind probability. It is what should happen in an ideal situation.

What does it mean for events to be independent in probability?

Back

Independent events are those whose outcomes do not affect each other. The occurrence of one event does not change the probability of the other.

What is the difference between theoretical probability and experimental probability?

Back

Theoretical probability is based on expected outcomes, while experimental probability is based on actual results from experiments.

How do you calculate the total number of outcomes when rolling two dice?

Back

Total outcomes = 6 (for the first die) x 6 (for the second die) = 36.

What is a sample space in probability?

Back

A sample space is the set of all possible outcomes of a probability experiment.
